According to one or more exemplary embodiments, the object may select a predetermined content based on a user input. The device may be connected to a service for reproducing the content which is selected by a user input to the object. For example, the object may include a play list which includes at least one content. The device may output a preview image of a moving picture which is included in the play list as a cover flow, when outputting the object. However, the object is not limited to the exemplary embodiment.

Hereinafter, exemplary embodiments will be described in detail with reference to accompanying drawings.

FIG. 1 is a schematic diagram of a structure which is configured to sharing content information, according to an exemplary embodiment.

According to the present exemplary embodiment, an external device 110 may transmit information which relates to at least one content reproduced on the external device 110 to a device 100.

For example, the external device 110 may broadcast a packet which includes tag information 120, such as, for example, a title of a song played by the external device 110, via short-range wireless communication. In particular, broadcasting of the packet via short-range wireless communication may refer to transmission of the packet so that an arbitrary device may receive the packet.

In an exemplary embodiment, the packet includes the tag information 120, that is, the tag information 120 is inserted in a field of the packet. For example, the tag information 120 may be inserted into at least one from among a service set identifier (SSID) field in a beacon frame and a vendor specific information element (VSIE) field of IEEE 802.

The tag information 120 may include information which relates to content. In particular, the information about the content denotes information which relates to content provided on the device. For example, if music content is provided on the device, the tag information 120 may include, for example, any one or more of a title, an artist's name, an album's name, and a producer's name of the song played on the device. As another example, if game content is provided on the device, the tag information 120 may include scores which relate to the game content.

Short-range wireless communication is a wireless communication method which is capable of transmitting/receiving data within a relatively short distance. According to the present exemplary embodiment, the device 100 may directly receive the packet which is transmitted from the external device 110, or the device 100 may receive the packet via a repeater. For example, when the external device 110 transmits the tag information 120 to an access point (AP) connected via a wireless fidelity (WiFi) communication method in infrastructure mode, the AP may insert the tag information 120 into an SSID and broadcast the tag information 120. However, the exemplary embodiments are not limited thereto.

If a connection of near field communication between the external device 110 and the device 100 does not include the repeater, the communication between the external device 110 and the device 100 may be performed by using a direct communication method. Direct communication between devices denotes that the devices may transmit/receive data directly to/from each other. The direct communication method between the devices may include any one or more of Bluetooth communication, ultra wideband (UWV) communication, ZigBee communication, and WiFi direct communication included in wireless LAN communication in ad-hoc mode. However, the exemplary embodiments are not limited to the above examples. That is, the direct communication method between devices may be referred to as any one or more of a machine-to-machine (M2M) communication method, a device-to-device (D2D) communication method, and a peer-to-peer (P2P) communication method.

The device 100 may receive information about content from at least one external device 110. The device 100 which receives the information about the content may provide a user with the content by using the information about the content. In particular, the device 100 requests, from the server, an object which relates to using the service providing the content, and may receive the object for using the service from the server. The device 100 displays the object for using the service, and may provide the user with the service by using the displayed object.

For example, the device 100 may receive the tag information 120 that is broadcasted by the external device 110. The device 100 that receives the tag information 120 may provide the user with the content by using the tag information 120. For example, when the device 100 receives the tag information 120 which includes a title of a song, the device 100 may reproduce a sound source corresponding to the title. In particular, the device 100 may transmit, to the server, a request for a sound source reproduction service in order to provide the service of reproducing the sound source, and may receive an object for using the sound source reproduction service.

In the exemplary embodiments, the device 100 and the external device 110 are distinguished by their operations according to the exemplary embodiments, and a device may perform as both the device 100 and the external device 110. In particular, the device 100 may receive the tag information 120, and at the same time, the device 100 may broadcast tag information which includes information about content provided via the device 100.

The device 100 and the external device 110 are capable of performing data transmission. The device 100 and the external device 110 may be the same kind of devices or different kinds of devices. The device 100 and the external device 110 may be any one or more of various devices, for example, mobile phones, smartphones, laptop computers, tablet computers, handheld PCs, electronic book terminals, digital broadcasting terminals, personal digital assistants (PDAs), portable multimedia players (PMPs), navigation systems, and smart televisions (TVs). However, the device 100 and the external device 110 are not limited thereto.

FIG. 2 is a flowchart which illustrates processes for broadcasting content information from the external device 110.

In operation S210, the external device 110 may generate tag information which relates to content provided via the external device 110.

The external device 110 may generate the tag information which relates to the content provided to the user of the external device 110. In particular, the content provided to the user may include any one or more of various contents, for example, movies, music, games, and exercise management services.

For example, if movie content is reproduced on the external device 110, the external device 110 may generate tag information which includes any one or more of a title of the movie, a genre of the movie, and names of actors starring in the movie. In this case, the external device 110 may generate tag information which includes information extracted from metadata of the reproduced movie content.

Then, in operation S220, the external device 110 may insert the tag information in a field of a packet that is transmittable via short-range wireless communication. For example, the tag information may be inserted in an SSID field or a VSIE field.

Then, in operation S230, the external device 110 may broadcast the packet in which the tag information is inserted via short-range wireless communication.

According to the present exemplary embodiment, the device 100 may directly receive the packet which is transmitted from the external device 110, or the device 100 may receive the packet via a repeater. For example, when the external device 110 transmits the tag information to an AP which is connected via a WiFi communication method in infrastructure mode, the AP may insert the tag information in an SSID and broadcast the tag information. However, the exemplary embodiments are not limited thereto.

If a connection of near field communication, short-range communication, or short distance communication between the external device 110 and the device 100 does not include the repeater, the communication between the external device 110 and the device 100 may be performed by using a direct communication method. Direct communication between devices denotes that the devices may transmit/receive data directly to/from each other. The direct communication method between the devices may include any one or more of Bluetooth communication, UWV communication, ZigBee communication, and WiFi direct communication included in wireless LAN communication in ad-hoc mode. However, the exemplary embodiments are not limited to the above examples.

FIG. 3 is a diagram which illustrates processes for inserting tag information which includes content information in a packet via the external device 110, according to an exemplary embodiment.

The external device 110 may generate tag information 350 by extracting data from content 310 which is provided on the external device 110. In particular, the content 310 provided on the external device 110 may include any one or more of various types of content, such as, for example, music content, game content, e-Book content, and movie content.

If the content provided on the external device 110 includes music content, the external device 110 may generate the tag information 350 which includes, for example, any one or more of a title, an artist's name, an album's name, and a producer's name of the song which is playable on the external device 110.

Further, if the content provided on the external device 110 includes game content, the external device 110 may generate the tag information 350 which includes score information of the game provided on the external device 110.

Still further, if the content provided on the external device 110 includes e-Book content, the external device 110 may generate the tag information 350 which includes any one or more of a title, an author, and a genre of the e-Book provided on the external device 110.

In addition, if the content provided on external device 110 includes movie content, the external device 110 may generate the tag information 350 which includes, for example, any one or more of a title, a genre, and actors starring in the movie provided on the external device 110.

However, one or more exemplary embodiments are not limited to the above examples.

According to an exemplary embodiment, the tag information 350 may include static data 320 and/or dynamic data 330.

According to the present exemplary embodiment, the static data 320 may denote data that may be defined based on the content, for example, any one or more of a category of the content, a genre of the content, and information stored in metadata of the content.

Further, according to the present exemplary embodiment, the dynamic data 330 may denote data that may vary based on the user or generation of the tag information, for example, a rank and/or a history of the user using the content.

The tag information 350 may not necessarily include both the static data 320 and the dynamic data 330. The tag information 350 may include one of the static data 320 and the dynamic data 330, or both of them.

The external device 110 may insert the generated tag information 350 in a packet 340 that is broadcasted via short-range wireless communication. In particular, the static data 320 and the dynamic data 330 may be inserted in different fields of the packet 340, according to the present exemplary embodiment.

FIG. 4 is a flowchart which illustrates processes for sharing content information by the device 100, according to an exemplary embodiment.

In operation S405, the device 100 may receive, from an external device, information about at least one content which is reproduced by the external device 110.

In particular, the information about the content may include information that identifies the content. For example, if the content includes music content, the information about the content may include a title of the music. However, the exemplary embodiments are not limited thereto.

According to the present exemplary embodiment, the information about the content may include tag information about the content. For example, the information about the content may include tag information which is extracted from metadata of the content.

According to the present exemplary embodiment, the information about the content may be included in the packet that is broadcasted from the external device 110 via short-range wireless communication. For example, the information about the content may be inserted in an SSID or a VSIE broadcasted from the external device 110, and then transmitted. In this case, the device 100 receives the packet that is broadcasted from the external device 110 via short-range wireless communication, and may extract the information about at least one piece of content from the packet. In the specification, the term ‘broadcast’ refers to transmission of information or a message from one place or one device to a plurality of devices or an arbitrary device.

Then, in operation S415, the device 100 may request, from a server, a service which relates to the information about the content which is received from the external device 110. For example, if the information about the content includes a title of at least one moving picture, the device 100 may request a service about the moving picture reproduction from the server.

In particular, according to the present exemplary embodiment, when the device 100 requests the service from the server, the device 100 may transmit the information about the content to the server. In response to the request which is received from the device 100, the server may generate an object for using the service which relates to the information about the content. For example, if the server receives the information about content including song titles such as “Arirang” or “Gangnam Style”, the server may generate an object which facilitates a capability of the device 100 to reproduce the songs “Arirang” and “Gangnam Style”.

Further, according to another exemplary embodiment, the device 100 may determine, from among a plurality of applications which are installed in the device 100, an application which is usable for reproducing the content which is reproduced on the external device 110. In particular, when device 100 requests the service from the server, the device 100 may transmit information about content, which includes information which is usable for identifying a determined application. The server may generate an object for using the service by using an application that may reproduce the content, from among a plurality of applications which are installed in the device 100, based on the information which is usable for identifying the application.

For example, if the external device 110 reproduces the music through “a music playing service 1” by using “a music playing application 1” and the device 100 includes “a music playing application 2” that may provide the user with “a music playing service 2”, the server may generate an object for using the music playing service via the “music playing service 2”.

Further, according to another exemplary embodiment, the device 100 may identify a service account that has an authorization to use the content reproduced on the external device 110. The device 100 may request, from the server, a service that requires a log-in registration, by using the identified service account.

In addition, referring also to FIG. 14, if there is no service account having an authorization to use the content reproduced on the external device 110, the device 100 may output a user interface for buying a usage authority via an output unit (also referred to herein as an “output component”) 1320 of the device 100. For example, if the external device 110 reproduces music and the device 100 does not have a service account for reproducing music, the device 100 may output a user interface for buying a usage authority of the lowest price for reproducing the music.

Then, in operation S425, the device 100 receives the object for using the service from the server, and in operation S435, the device 100 outputs the object. The device 100 may provide the user with the service which relates to the information about the content which is received from the external device 110 by using the output object.

According to another exemplary embodiment, the device 100 may receive information which is usable for identifying the external device 110, instead of the information about the content, in operation S405. Then, the device 100 may request a service which relates to the external device 110 from the server in operation S415. In particular, the server may acquire information about content reproduced on the external device 110 or information about the service provided on the external device 110. For example, the external device 110 may periodically update information about the content reproduced on the external device 110 or the service provided on the external device 110 to the server. The server generates an object for reproducing the content reproduced on the external device 110, and transfers the object to the device 100. The device 100 may output the object which is received from the server, and may provide the user with the service by using the output object.

FIG. 5 is a flowchart which illustrates processes for reproducing content by using tag information in the device 100, according to an exemplary embodiment.

In operation S410, the device 100 may receive a packet that is broadcasted from the external device 110 via the wireless communication.

According to the exemplary embodiment, the device 100 may broadcast tag information about the content provided via the device 100 based on a user's selection via short-range wireless communication. According to the present exemplary embodiment, the device 100 may perform operations S410, S420, S430, and S440 in a case in which the tag information is broadcasted. In particular, in order to receive the tag information from the external device 110, the user of the device 100 may broadcast the tag information which is generated from the content reproduced on the device 100.

Then, in operation S420, the device 100 may acquire and/or extract the tag information from the packet.

In particular, the device 100 may decode the packet, and may acquire the tag information which is inserted in a predetermined field of the decoded packet.

In addition, in operation S430, the device 100 may determine a list of contents to be provided based on the acquired tag information.

The device 100 determines the content by analyzing the tag information, and may determine a content list which includes the determined content.
